The simplest and most inexpensive unit to get Caller ID time, date, name and number from multiple phone lines into a computer for pop-up screens and order entry. The choice of Domino's Pizza and many food service point-of sale (POS) solution providers to integrate Caller ID into delivery and take-out modules. Also use as a direct replacement for old model Caller ID interface units such as the TCI MLX-41 & MLX-82, Bek-Tel PC-4 & PC-8, and Comdial Caller ID adjunct units. POS series units connect via RS232 serial interface and are available in 2, 4, and 8 lines models. Four and eight line units chain together for larger installations up to 96 phone lines. Avaliable
in Serial Port and Ethernet Link models.

POS units can be used with any multi-line telephone system as long as the main phone lines coming into the building are analog. Incoming phone lines plug into the unit and a serial or Ethernet cable connects it to a PC. Modular input and output jacks are provided so that all connections are a snap. The unit connects the same way even if a digital system, KSU, or PBX is present. If more convenient, units can even be connected in parallel with incoming phone lines.
